4 Channel Bidirectional Logic Level Shifter

This 4 channel bidirectional logic level shifter allows mixed voltage
parts to be used in the same system.

Each bi-directional level shifter can convert signals from 1.5V to 18
V in both directions. The module provides a set of four channels that
for voltage conversion. It can be used for a variety of four pin
digital interfaces and is ideal for use with I2C, SPI and TTL serial.

Use this logic shifter when connecting a 5V microcontroller to a 3.3V
component or the other way around.
